Google brought pedometer functions to Android with the recent release of Android 4.4 (KitKat), but that’s not necessarily enough for smartphone owners who want to track their fitness routines. Google may be aware of the desire for more fitness information, though. Google Operating System has discovered leaked code (shown below) for a future “Fitness API” that would supply apps with activity data from an Android device’s sensors.

Android 4.4 supports new sensors for detecting and counting steps. These sensors are implemented in hardware and are only available on Nexus 5. This new Fitness API for Android will allow applications to view and edit fitness data. There aren’t any clues as to when the API would be ready, and it’s uncertain whether the software is tied to either a new OS revision or a Google Play Services update. However expect your favorite Android fitness app becomes much more sophisticated in the near future.
